BED HEATER Filed June 7, 1946 Jahn C. Gerdes Patented Gct. 26, 1948 UNITED STATES PATENT OFFICE 1 Claim.

1 This invention relates to a bed heater and it is an object of the invention to provide a device of this kind adapted to be suspended below the bed to keep the bed, and more particularly the mattress, warm and dry.

It is also an object of the invention to provide a heater of this kind of suitable length and which is adapted to be supported by a bed below the mattress or other body supporting structure at substantially the transverse center of the bed, with the longitudinal axis of the heater disposed lengthwise of the bed.

A still further object of the invention is to provide a heater for a bed for support directly by the bed and wherein the structure of the heater is such as to permit the use of the heater without any rays from the heater annoying the occupant of the bed.

It is well known that the mattress and covers of a bed will absorb humidity from the air, and it is a still further object of the invention to provide a heater of a character to be supported in free air close to the under side of the mattress to achieve complete heat penetration, whereby the mattress or other parts of the bed are not only dried and warmed but the heat emanating from the heater will also warm the surrounding air which will envelop the entire bed and at the same time warm the air within the bedroom.

The invention consists in the details of ccnstruction and in the combination and arrangement of the several parts of my improved bed heater whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view side elevation illustrating a heater constructed in accordance with an embodiment of the invention and in applied position, an associated bed and mattress being 4diagrammatically indicated;

Figure 2 is an enlarged view partly in section and partly in elevation of the device as comprised in Figure 1;

Figure 3 is a view in end elevation of th'e heater as comprised in Figure 1, the associated supporting element or bed slat being shown in fragment;

Figure 4 is a fragmentary view partly in elevation and partly in section illustrating a further means for holding the heater in working position.

In the embodiment of the invention as illustrated in the accompanying drawings, the heater comprises an elongated cylindrical tubularvmember or container I of re-proof material and preferably aluminum.

Positioned within each end portion of the member or container I is an incandescent electric bulb 2 which engages in the usual manner with' a light socket 3 below the bed or otherwise secured, as at 4, to a spacer plate 5 of insulating material which is snugly tted within the adjacent end of the member or container I.

This plate 5 is securely held in desired position within the member or container I by the screw members 6 or the like which pass through the wall of the member or container I and engage Within the peripheral portion of the plate 5.

The plate 5 extends partially within an end of the tubular member or container I and the outer face of said plate has held thereto by the nuts 'I engaging the outer ends of the bolts 4, the diametrically opposed and aligned arms 8 and 9 carried by the conventional receptacle Ill,

The arm 8 is of a length to extend beyond the periphery of the member or container I and is provided in its outer portion with an opening II whereby said arm may be readily engaged with the bill I2 of a suspension hook I4, herein disclosed as secured to the under surface of one of the slats S comprised in the bed structure. It is believed to be obvious that the mounting oi' the suspension hook I4 may be in connection with any convenient part of the bed as determined by the structure of the bed.

leading from the socket 3 and out through the receptacle I0 is the usual conductor or cable I5. The two light sockets 3 are connected in series by the cable or conductor I5 and one of the lamp sockets also has leading therefrom a conductor or cable I6 adapted for communication with a suitable source of electricity, such as a conventional wall socket.

The suspension hooks I4 are preferably positioned in alignment at the transverse center of the bed in such spacing lengthwise of the bed as determined by the length of the member or container I which is preferably of a length in excess of one-half of the length of the bed.

The Wall of the member or container I readily radiates heat so that the heat generated within the member or container l by the bulbs 2 will rise and penetrate the mattress M upon the bed and ultimately the bed clothing. This is of importance, particularly on damp and chilly days and especially for the benefit of persons suffering from such ailments as stili joints, rheumatisrn, lumbago, and the like.

It is believed to be self-evident that the heater, when in use, will not only warm the mattress but will also serve to keep the room temperature at a comfortable level.

While the upstanding arms 8 can be employed to advantage with the supporting hooks I4, it is to be stated that, if desired, as illustrated in Figure 3 of the drawings, a chain or other flexible member may bethreaded through' the opening Il of each of-saidlarms 8 and be engaged around a bed i.,

slat or other convenient part of the bed.

In hereinbefore referring to the slats, it is to be understood that this is to embrace any desired form of bed bottom.

From the foregoing description it is thought to be obvious that a bed heater constructed in accordance with my inventionos particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.
